Hepatization of the gallbladder is a recognized sonographic feature that can be observed in case of bile duct obstruction [1]. In hepatization, the gallbladder “mimics” the echotexture of the adjacent liver, appearing as a kind of camouflage (Fig. 1). This appearance is due to the accumulation of tumefactive sludge, rendering the gallbladder similar in echogenicity to the hepatic parenchyma (Fig. 2) [2]. Occasionally, it leads to nonvisualization of the gallbladder on sonography [1]. Biliary system diseases are a frequent cause of abdominal pain [3]. Nowadays, sonography is considered the initial imaging modality of choice for evaluating the biliary system [2]. The normal gallbladder has anechoic content and thin echoic wall [3]. In the setting of cholelithiasis, the presence of obstructing calculi, wedged in the gallbladder neck or in the common bile duct, leads to excessive accumulation of
